Product Overview

The IC695ALG704-DC is a high-precision control interface for the PACSystems RX3i platform, offering four independent analog output channels. Each channel is software-configurable to provide either voltage or current signals, making it suitable for controlling a wide variety of field devices such as control valves, motor actuators, and VFDs. Featuring 16-bit resolution and sub-millisecond update rates, this module ensures smooth, accurate control for advanced closed-loop control systems.

Technical Specifications

Key Features

• High-Resolution Precision: 16-bit digital-to-analog conversion enables fine adjustments, perfect for applications in PID control and other precise processes.

• Per-Channel Configuration: Independently configure each channel for different signal types and ranges (voltage or current).

• Rapid Response: The sub-millisecond update rate ensures real-time control with minimal signal lag.

• Advanced Diagnostics: Provides fault reporting like open-wire detection and short-circuit protection for improved maintenance.

• Isolated Performance: Electrical isolation prevents ground loop interference and protects the controller from electrical noise or surges.

FAQs

What type of terminal block is required?
The IC695ALG704-DC uses a 36-terminal Box-style (IC694TBB032) or Spring-style (IC694TBS032) terminal block. An extended-depth terminal block cover is needed for proper fitment.

Do I need an external power supply for this module?
Yes, the module requires an external 24 VDC power supply to drive the current loops and power the analog output circuits.

Can I install this in any RX3i backplane slot?
This module uses the PCI bus, so it must be installed in a PCI-capable slot within the RX3i Universal Backplane (IC695CHS series). It is not compatible with Serial-only expansion racks.

What does the "-DC" suffix signify?
The "-DC" suffix indicates a specific hardware revision, ensuring full compatibility with the original IC695ALG704 series while meeting the latest component standards.
